Does Firebird work on WinCE?
There is no official port, but John Bellardo created a port of Firebird 1.0 client at the time. Unfortunately, he has no resources to give any support for it, so please don't try to contact him about it. He agreed to give us the files he created and host them on FirebirdFAQ (to save his bandwidth). You can download the MSVC project files and precompiled Firebird 1.0 client here:
The file is about 19MB. Please remember that this is unsupported, unofficial port and whatever you want to do with it: you're on your own. If you'd like to port some newer version of Firebird to WinCE, please contact Firebird developers directly at developer mailing list (see FAQ #65 for details).
